Record 2 1997-11-17

English

Subject field(s)
  • Plastics Manufacturing
CONT

The [intermittent extrusion] process has three subcategories : the reciprocating screw method, the ram accumulator method, and the accumulator head method.... The ram accumulator method, which is no longer in widespread use, is intended for heavy parts weighing 2 kg or more. Much like the reciprocating screw, the system is used to quickly extrude heavy parisons that might sag or draw down from gravity. The accumulator is a reservoir mounted alongside the extruder. A piston or plunger pushes the melt through the extrusion head. Unlike the reciprocating screw, melt that enters the reservoir first is the last to leave.
